How the Mineral'35 index is built
Liquidity, float, and custody standards — the quiet rules behind the headline return.
Mineral'35 holds up to thirty-five liquid digital assets. Constituents must clear market-cap, volume, and custody bars before they enter, and they can leave when those bars are missed.
Weights are capped so a single name cannot dominate the book. Bitcoin and Ethereum remain the core, but the rest of the sleeve is there so the index represents the market as it actually trades — not a two-asset bet.
Rebalancing is scheduled, not emotional. When a coin runs too far, the index trims. When a name falls out of the eligible set, it is replaced. That is the whole mechanism.
Past performance of the index is not a promise. It is a record of a rules-based book. Use the calculator as a planning tool, not a forecast.
